POWEBEDRIVEN i VEHICLE. Applicationifiled A ril 5, 924.'- Serial No. 704,444.

To all whom it may concem: preferably arranged so as to partly move .Be it known that I, ALBERT Bnn'ruow and-also turn laterally with. the same. The ENNINGER, residing at Berlin-Wilmersparts of the casing that turn with the wheels dorf, Prussia, Germany, have invented oer may be arranged to carry the lights or protainv new, and useful Improvements in jectors, these projectors being also encased Power-Driven Vehicles, of which the folin casings of stream line form. By thus lowing is'a specification. arranging the projectors to. turn with the stream line corresponding substantiall to i th d i i whi h This invention relates to motor driven wheels t e li-ghtfis always thrown in the vehicles of all kinds both for railways and direction in which the wheels are turned.

roads. The object of the invention is .to The wheels may be advantageously arproduce a vehicle to whose travel the least ranged-entirely or partly in the trunk of possible resistance is offered by the air. This stream line form of the vehicle body or they is accomplished b giving the bod of the may be entirely or partly placed in projectvehicle substantially the shape of alf the ing portions attached to the trunk;

The entire trunk a I the seats are arranged being substanti y The'bottom of the trunkis substantially parby a generatrix in the shape of a stream line. ab th d h d d t lin i Fi 1 h The shape thus produced is substantially theform. of half a surface of revolution similar to that of one-half of n l ng t generated by a stream line, substantially drop of fluid, the front of the body in which similar to that of an elongated drop of fluid.

The. bottom e $0 81 0 make i better ada e human surface d of the trunk a, that is the part beoccupants. Theaforesaid y is preferably jnea'th the-dash and dot line is flat up to the provided with a bottom that is flat at its point where the .cross section is largest, that i Wi Portion but is curved near the end of is up to the plane AB,- and at the rear it.

the trunk of the body, he u v ture incre e is curved, the curvature transversely of the ing towards the end; The. edgesi' 'at which vehicle increasing towards the end particu-' sists in making the other parts of the vehicle depressed. Radial sections taken the body is connected to the bottom of its larly at f. The trunk a of the vehicle body trunk are also rounded in accordance with has, as already mentioned, substantiall' the v the invention a 5 form of a surface generated by the rotation A further feature- 0f the invention 0011- of a stream line but its sides are 1slightllly a on t e which are not situated within the trunk of dash and dot lines indicated-in Fi 1 all the vehicle body in the shape of surfaces have substantially the form of sections of generated by a generatrix in the 0 of t half a body generated by the rotation of a streani line corresponding to that of an stream line. Horizontal sections -throu h.

The and that lie outside a trunk of the vehicle rear wheels 0 are partly-arranged in-projec-r body. The steps and connecting portions 'tions or fins g 'connected to the trunk of the "which connect the casings of the wheels with vehicle body. The front wheels b are 'arthe trunk also have. stream line form. ranged in casings h in the front and rear of The stream line casings of the wheels are which there are separate small casings k [and h respectively. These three casings k,

h and h taken together, form a stream line body, preferably a body generated by the rotation of a stream line but with considerably depressed sides. .The middle portion h is arranged. to turn with the wheels. Placed upon the middle portion is a casing z of stream line form for the lamps or pro'ectors. These pro'ectors are thus arrange to turn with the w eels so that the light is always thrown in the direction in which the wheels are turned.

The front sections. h of the casings that envelop the-wheels are interconnected by a crosspiece h which also has the. form of a stream line. r

The front axle b 'is also enclosed in a casing is of streamline .form, this casin is being bevelled at the sides so as to em le" the wheels I) to be ,turned for. the purpose of steering the. vehicle. *"The cross piece it may be connected to the trunk of the vehicle body in anyldesired way, such, for example,

as by suita e supports (not shown) extending from casin k. 3 he section 3 is connected to the trunk a by a connecting piece m whose periphery also has the form of a stream hne. The

steps 11. are also of stream line shape. About. two thirds of the wheels are enclosed in theircasings or in the'trunk of the vehicle.

I claim 2-,

1. In an.automobile, a bod wheels for carryin the body, and in com ination with said bo y a separate casing having stream line form closely housing. some of said wheels.

. 2. In an automobile, a' body, wheels for carrying the body, and in combination with a said wheel a casing having stream line form and closely surrounding the said wheel at least a. half of itsheight.

3, Inan automobile a body having substantially the form of half a surface generated by the rotation of a stream line, wheels for carrying the vehicle, and in combination with a said wheel a separate easing also having stream line form and closely surrounding the said wheel.

4. In an automobile, wheels for carrying the automobile, means for uniting two of said wheels, and a separate casing of stream line form, comprisin the said means.

5. In an automobi e, wheels for carrying said automobile, a main casing, an axle for 8 -parts, one of w liCll being movable with the said wheels.

7. In an automobile, wheels for carrying the automobile and in combination with one of said wheels, a casin having streamline form, and being divi ed into three parts. one of which being movable with the said wheel, another arranged before the said wheel and the third behind the said wheel.

8. In an automobile, wheels for carrying the automobile and in combination with a said wheel, a casing having stream line form, with projections also of stream line form, wheels for carrying the vehicle and a part of saidwheel being situated inLa said projection.

'9. .In an automobile, wheels for carryin said automobile, and in combination witi one of said wheels, a separate'casing having stream line form and enclosing said wheel for two-thirds of its hei ht.

In testimony whereo I have atiixed my signature in presence of two Witnesses.
